Restoring Painted Black Grout with Tile Doctor Grout Colourant in Richmond South-London
This customer from Richmond called Tile Doctor due to see what could be done to improve the Grout on their Ceramic tiled floor which had been installed throughout the ground floor. Having previously called in a cleaning company to deep clean the tile and grout it now needed remedial work to restore the appearance of the grout. The grout had originally been painted black and this had been badly scrapped by the cleaning company leaving it in a bad state, also he felt the tiles could had not been cleaned properly either.
Having visited the property to survey the floor I was able to reassure the customer that the Grout could be restored and discussed the benefits of the Tile Doctor Grout Colourants. These colourants are made from epoxy and are much more hard wearing than the paint-based product which we usually only recommend for touching up.

I worked out a quote for deep cleaning the tiles and colouring the grout with a black colourant to restore the appearance of the floor. After reviewing and answering any questions they quote was accepted and a date scheduled.
Deep Cleaning a Ceramic Floor Tiles
I started off by checking the whole floor for missing grout and then raking out the problem areas and re-filling using a fast-drying black grout.
Attention then turned to deep cleaning the Ceramic floor tiles starting with the application of a medium dilution of Tile Doctor Pro-Clean. This was left mopped onto the floor and then left for ten minutes before being worked into the tiles using a Victor Trojan floor buffer fitted with a Black scrubbing pad. The pad is run over each tile several times moving slowly with small circles to ensure the floor was getting a good scrub and I was getting everything off.

There was also a small toilet area to be done which was too small for the Victor machine so and I did this using the same process but with a handheld Dewalt polisher fitted with with a 6-inch black scrubbing pad. Once an area had been scrubbed it was rinsed with water and then all the liquids extracted using an industrial wet vacuum.
Once the floor was cleaned work started on epoxy sealing the grout using Tile Doctor Black epoxy grout colourant, this not only seals the grout but also gives everything a uniformed colour the whole way through. I didn’t need to wire brush and clean the grout on this occasion as the grout had already been cleaned earlier.
In total It took three coats of Black grout colourant to achieve the desired effect and nine hours of hard work on my hands and knees.

When finished the Ceramic tiled floor was cleaner, the black grout had been restored and my customer was very happy and requested I return to renovate two bathrooms. For aftercare cleaning I recommended they use Tile Doctor Neutral Cleaner which is a mild yet effective product.
